It should be wider than the 2 uprights so impossible to hit anyone forward............maybe launch onto the hood behind you if you get rear ended. <img src="/forums/images/graemlins/smile.gif" alt="" /> That baby is on there and very easy to get off. When it's tightened, it's pulled up tight to the uprights on each end. I had mine locked to one of the uprights with a cable bicycle lock. Very simple and effective.
